Black arrow
indicates first measurement of the day (after that logging went out); red arrow
indicates the "big dip" (dotted circle) due to the partial
solar eclipse with a minimum around 12h40 MEZT during very sunny

in our environment (Leiden, near west coast

be seen on the
highly detailed and unique website
of
"Mister

Ton Peters in Spijkenisse, a city SW. of Rotterdam, app. 45 km.
south of my location in the same province. See:
